In July 2005, OSNews reviewed the 1.0 version of what was then YellowTAB Zeta. I concluded: "I have a clear-cut impression of what Zeta R1 is: it is by far the best 'distribution' of BeOS currently available. The hardware support is, when compared to r5, significantly better. Stability-wise, Zeta R1 is a huge leap forward when compared to older versions. Some areas still need work; but they are mostly minor things, nothing that will stop you from using this operating system as your full-time, primary system." A lot has changed over the past 15 months; YellowTAB went belly-up, Magnussoft took over the development of Zeta, and to top it off, Zeta went multiuser. Not too long ago, Mangussoft released Zeta 1.5; here is my review.
